There are two types of light switches in cars: one is a rotary lever switch, and the other is a rotary knob switch. Currently, rotary lever switches are predominant in most cars. Each light has a corresponding position on the switch; simply turn it to the specified position, and the corresponding exterior light will illuminate, while the dashboard will also display the corresponding indicator. The position light (also known as parking light) is a warning light, white at the front and red at the rear, usually installed along the edges of the car's roof. This indicates both the height and width of the vehicle. Low beam and high beam headlights are typically used in combination, but for everyday driving, turning on the low beam is usually sufficient to meet the driver's needs.

In my daily experience of driving a car, the light switch is usually located on the control lever to the left of the steering wheel. This lever is typically connected to the turn signals. You can twist the knob at the end of the lever to switch between lighting modes, such as turning it once for side lights and again for headlights. Newer cars might have automatic functions set via central console buttons, but the steering wheel lever remains the mainstream. The key is not to overlook it when getting in the car—develop the habit of checking the light status immediately and turning on the headlights at night to ensure visibility and safety. If you can't find it, refer to the owner's manual; most brands have similar designs with unified positions for driver convenience to prevent accidents. Some older models might have different positions, such as on the center console, but it's not hard to figure out with a little exploration.

I remember when I first bought my car, the position of the light switch confused me for a while. Just twist the lever on the left side of the steering wheel, and it's easy to operate without interfering with driving. If the car is a high-end model, the switch might be hidden in the central control screen menu, requiring a few more taps on the screen to find it. It's recommended to manually check the light status before driving at night—don't rely solely on automatic mode in case it fails. Once the position is set, turning on the lights becomes natural and saves energy. Extending to daily maintenance, regularly clean the switch to prevent dust from jamming and affecting its use.

The car light switch is quite simple, located on the left lever near the steering wheel. Just twist it to turn on the night lighting with one click, ensuring safe driving without hassle. In modern models, it's often integrated into the central control screen, but the steering column lever remains the most commonly used. New drivers can easily get familiar with it by trying—no need to overthink. The key is not to forget to turn on the lights, otherwise poor visibility can lead to more accidents and greater risks. Automatic functions are convenient; set them up properly to avoid frequent manual adjustments.
